I found this and it's worked:

This occurs when MySQL runs out of locks, which for an InnoDB database occurs when the buffer pool is full. You can fix this by increasing the size of the buffer pool, by editng the innodb_buffer_pool_size option in my.cnf (my.ini), to set innodb_buffer_pool_size to a number higher than the default (which is typically 8M); for instance:

  innodb_buffer_pool_size = 256M

Thanks for your help.

Also, if manual DELETE FROM statements will not work, try to clear tables with

TRUNCATE TABLE syslog;
TRUNCATE TABLE event_log;
TRUNCATE TABLE snmp_trap_log;
TRUNCATE TABLE audit_log;

Best regards,

Try to connect to your database with mysql client and clear log tables manually by executing the following queries:

DELETE FROM syslog;
DELETE FROM event_log;
DELETE FROM snmp_trap_log;
DELETE FROM audit_log;

Then run upgrade process again.
